I love @jake_social's idea of recycling the cardboard from the empty Prusament spools and making storage boxes out of them!
Only the design didn't seem quite complete to me.
So I made a few small changes:
I transferred the design from the lid to the bottom of the box so that the overall look is consistent.
I also hollowed out the base and lid a little to create a little more space while also saving filament.

The author remixed this model.
The bottom of the box now also fits into the design.
The fingergrip have been removed from the lid.
